| Abstract: | A certain kind of approximate linear relationship is found between corrosive temperature (T) and corrosive time (H) for metal structure, within a certain range of temperature. It is called the T H curve in this paper, which is similar to the S N curve in the fatigue field. On the basis of T H curve, the author deduces the formula of calendar life for corrosion damage of metal under many kinds of medium surrounding.As for the form, it looks like the Miner theoretical formula in fatigue field. Using this formula, the calendar life for corrosion damage of metal can be estimated simply under varied complicated medium surrounding. |
